Here lie the birds killed while striking a set of buildings surveyed during the migration season in 2013 in Washington D.C. The birds were picked up by the group Lights Out Washington D.C.

The red maple, Acer rubrum, often one of the most dominant trees in deciduous woods in the East. It blooms very early in the spring and provides pollen and nectar to the set of bees, and flower flies, that come out early.

Another tree flower loving beetle from South Africa this one a buprestid, Acmaeodera virgo. Collected widely in bowl traps and in trees in Kruger National Park. Photo by Kelly Graninger.

Ohio Buckeye, Aesculus glabra. Buckeye's...one of the nice little acknowledged providers of pollen and nectar in forested environments. Specimen and photos by Helen Lowe Metzman.

Lovely wasp from Kruger National Park. Again, not being a wasp person, I don't know the species. The group may be the sand wasp (Bembicini) . Photos by Anders Croft.

A large bright green with blue overtones Agapostemon from Badlands National Park. One of several species present there and very similar to A. virescens and a bit tricky to tell apart. Photo by Wayne Boo with help from Ben Smith on upping the Photoshopping techniques.

Two different specimens of Andrena geranii. A northernish species that appears to be a specialist on ....geraniums. Notable is the slight blue metallic sheen to the body. Aaman Dengis and Brooke Alexander took the pictures.

Not the best lighting, but this is Andrena gnaphalii....a interesting Andrena with a green tinge. From the Channel Islands off the coast of California. Photo by Anders Croft.

Another odd ball Andrena from the Channel Islands. This one is A. gnaphalli, collected as part of a larger study of bees in climatically vulnerable National Parks. An apparent Asteraceaea specialist with some glints of green and red instead of the normal black integument.

Sunflowers. Specifically, the genus Helianthus to separate out the other "sunflower" plants. Only found in North America. So tall and glorious that we have adopted many for our gardens. Thrusting skyward they telegraph their supply of pollen and nectar to the bees that only feed their young pollen of Sunflower. Here is one of them. The appropriately named A.

Pennington County, South Dakota, Badlands National Park

Andrena cressonii - Common, shows up almost everywhere in the spring. Secret identification tip of the day: There is a raised line slanting across the pronotal collar that is usually visible from one side of there other (depending on how the head is cocked). As you go west the legs tend to get very orange...is it a different species?

A bee that feeds its babies a restricted diet. In this case that diet is that of Geranium pollen. While I didn't check this specimen from Virginia those lovely pollen grains on its hind legs are very likely Geranium.

A very early spring bee, covered in pollen, collected by a homeowner in Bowie, Maryland

From the Great Smoky Mountains of Tennessee comes Andrena fenningeri, one of the very early spring bees, often associated with red maple bloom. In this case a male. Amber Reese took the picture and Elizabeth Garcia did the shopping.

Another member of the difficult to identify Trachandrena subgenus of Andrena. I think that I have the females sorted out (more or less) but the males...oi! This specimen from Maryland. Picture by Amanda Robinson.

An odd, dark Andrena bee of deep sandy areas that comes out in the middle of summer

Badlands National Park, South Dakota

Anthophora bomboides. Fuzzy . Faking the bumble bee look to fool birds into thinking they can sting like a bumble bee. Here is one from San Juan Island in Washington State. This species occurs throughout the continent....but....its look differs across that huge geographic range. Are they more than one species or not? Does anyone care? You?
